Enter the page thickness (mm) and the number of pages into the Calculator. The calculator will evaluate the Spine Width.

## Spine Width Formula

SPW = TP * P

Variables:

- SPW is the Spine Width (mm)
- TP is the page thickness (mm)
- #P is the number of pages

To calculate Spine Width, multiply the page thickness by the number of pages.

## How to Calculate Spine Width?

The following steps outline how to calculate the Spine Width.

- First, determine the page thickness (mm).
- Next, determine the number of pages.
- Next, gather the formula from above = SPW = TP * #P.
- Finally, calculate the Spine Width.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

page thickness (mm) = 5

number of pages = 6
